Material Composition Industrial-grade multi-layer PCB with high-reliability components. 64MB DRAM from qualified suppliers. Enhanced gold-plated connectors. Durable IEEE 1101 front panel construction.
Structural Characteristics Standard 6U VME form factor. IEEE 1101 front panel with injection/ejection mechanism. LED status indicators. P2 connector for MVME761. DRAM mezzanine connector for future expansion.
Working Principle The 266 MHz MPC750 accesses 64MB ECC DRAM through optimized memory controllers. The 1MB L2 cache minimizes memory access latency. The PowerPlus Architecture ASICs ensure efficient data flow between processor, memory, and I/O subsystems.
Installation Requirements VME64 chassis with adequate cooling and power for 64MB memory. P2 backplane must support MVME761 transition module. Proper grounding essential.
Usage Notes 64MB memory supports most demanding embedded applications. Regular ECC monitoring recommended. Ensure proper cooling for sustained 266 MHz operation.
